ing arms and to also provideimproved actuating means for moving these arms.

Another object of the invention is to provide' a stem which forms a portion of the actuating means with an improved manner of mounting so that as the same moves longitudinally it will have a rotary motion,

thus causing the leaf engaging arms to be moved. 7

Another object offthe invention is to so construct the support of the leaf engaging "arms and stem that the support may be revmoved when it is not desired to use the same.

- Another object of the invention is to so construct the device that it will be very simple in construction but atthe same time very efficient in operation.

- This invention is illustrated in the accompanying drawings, wherein Figure 1 is a View showing a piano in front elevation and provided with the improved leaf turning attachment; Fig. 2 is a view showing the piano in end elevation and provided with the improved leaf turning attachment; Fig. 3 is a perspective view of the support which is removably connected with the piano; Fig. 1 is a fragmentary view showing the manner of mounting the finger which engages the leaf engaging arms; Fig. 5 is a fragmentary sectional view taken along the line 5-5 of Fig. 1.

The piano 10 is of the usual construction of upright pianos and is provided with a socket 11 which is secured't'o the top as shown in Figs. 1 and 2. The book supporting bracket 12 is connected with the foot 13 of the supporting bar or strip 14 by means of a bolt 15 which-serves another purpose to be hereinafter brought outi This strip 1a Specification of Letters Patent.

is connected with the strip or wedge 16 which fits into the socket 11 to support the leaf turning mechanism in the position shown in Figs. 1 and 2. The forward end 17 of the wedge 16 extends beyond the strip 14: and is provided with an opening which is formed in alinement with an opening 18 formed in the upper arm 19 of the guiding strip 20. This guiding strip 20 is secured to the supporting strip 1 1 and has its lower end bent to form a foot 21 which is positioned above the foot 13 of the strip 14.

The leaf engaging arms 22, 23 and 24 are pivotally mounted upon the bolt 15 between the feet 13 and 21 and are separated by the dividing plates 25 and 26 which are positioned as shown in Fig. 5 with their rear ends passed through openings 27 and bent to lock the plates stationary. The inner end of the arm 23 is provided with a heel 28 which extends to such an extent that the heel will be engaged by the arm 22 when swung to the position shown in Fig. 3 and cause the arm 23 to be moved forward slightly. When the arm 23 is swung to turn the page which it engages, the heel will en gage the arm 2-1 and move it forwardly slightly. This is done, to bring the arms in the proper position to permit them to be swung upon the pivot bolt 15 and turn the pages.

In order to swing the arms, there is provided a stem 29 which is slidably mounted in the openings formed in the wedge 16 and arm 19 andhas its lower end portion fiattened and twisted as shown at 30. The stem is twisted as shown so that as the pin moves downwardly through the opening 18 the stem will be turned from the position shown in full lines in Fig. 3 to that indicated by dotted lines. An arm 31 extends from the lower end of the stem 29 and carries a pivotally mounted finger 32 which swings freely in one direction but is limited in its 'pivotal movement in the opposite direction by means of an abutment 33 shown in Fig. 4. It will thus be seen that when the stem returns to the position indicated by dotted lines in Fig. 3 the finger 33 will carry one of the leaf engaging arms with it but that when moving in the opposite direction the finger 32 will move pivotally and not move the second leaf engaging arm in case the finger strikes the second leaf engaging arm shown in Fig. 3.

when the stem is returning to the position shown in full lines in Fig. 3.

The lever 3st which forms part of the actuating mechanism is pivotally connected with the piano by means of the bearing 35 and has its forward end provided with a slot in which the stem fits as shown in Figs. 1 and 2 so that when the lever is moved the stem will be moved with it. This lever which is normally held in the position shown in Fig. 2 by meansof the springs 36 is connected with a rod 37, the lower end of which is connected with the bell crank lever 38. This bell crank lever 38 is connected with the foot treadle 39 by means of the rod 40 and it will thus be seen that when the foot treadle 39 is moved downwardly the bell crank lever 38 will be swung to raise the rod 37 and swing the lever 34 against the tension of the spring 36, thus moving the free end of the lever downwardly and carry with it the stem 29. I

WVhen this device is in use, the actuating mechanism is permanently connected with the piano and the music turning and supporting mechanism is only connected with the piano and actuating mechanism when it is desired to use the piano. After a book of music has been placed upon the support 12 the leaves of the book containing the piece it is desired to play are engaged by the arms 22, 23 and 24. After the first page of music has been played, the foot treadle 39 is pressed upon, thus moving the actuating mechanism to depress the stem 29. It is of course obvious that when the mechanism is in the initial position shown in Fig. 1 the arm 22 will be in a position to permit finger 32 to pass between the arms 22 and 23. 'As the stem 29 moves downwardly the finger 32 will first engage the arm 22 and the stem will then turn, thus swinging the arm 31 and causing the arm 22 to be moved to the position shown in Fig. 3. The foot treadle 39 is then released and the stem will be carried upwardly and return to the position When the arm 22 has moved to the position shown in Fig. 3 it willengage the heel 28 of the arm 23 and swing it outwardly a sufiicient distance to permit the finger 32 to engage the arm 23 when the actuating mechanism is again'o'perated to move the stem 29 downwardly and turn the second page of the music. the second page of the music is turned the heel 28 will engage the arm 24 and move it to a position where it may be enga ed by the finger 32. When it is no longer esired to use the piano the pin 16 is removed from the socket 11 and the music supportin and turning mechanism will thus be disconnectedfrom the piano and may be put away.
